WELL-DRILLING DERRICK.

Application filed. November 16, 1923.

T0 (171 whom it may 007L06'7'9t.

Be it known that I, DALLAS D. lVnR'rz- BERGER, a citizen of the United States, and a resident of the city of Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in ellDi'illing Derricks; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and

a to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to well drilling derricks especially adapted for drilling oil wells.

On account of the cost and inconvenience of securing steel, these derricks are now con structed of wood and braced by adjustable rods. Hitherto there has been great difficulty in providing a structure that would withstand the great vibrations arising from the drilling operation. Bolts and parts would work loose and drop, not only im pairing the structure, but frequently injuring a workman and sometimes causing death by their descent.

It is accordingly an object of this invention to provide a safe structure that will withstand the great vibrations due to drilling and in which the parts are so confined and secured that there is little liability of the same working loose and descending upon a workman.

With these and other advantages in view which will become more apparent in the following description and disclosures this invention comprises the novel structure and combination hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views,

Figure 1 is an elevational view of an oil well derrick with parts broken away.

Figure 2 is an enlarged fragmentary elevational view of an anchor lug for the bracing rods attached to the derrick.

Figure 3 is an enlarged sectional view upon the line 33 of Figure 1.

Figure 4 is an enlarged top plan view with parts broken away.

Figure 5 is an enlarged fragmentary elevational View of the derrick head.

Serial No. 675,043.

Figure 6 is an enlarged fragmentary ele vatioual view of the derrick head.

As shown on the drawings:

In referring now to the drawings which illustrate one embodiment of this invention, there is shown an oil well derrick which con sists in the present instance of four upright wooden standards 1. The lower ends of these standards are connected by wooden members 2 and at a suitable height so as not to interfere with the work are similar connecting members 3 which connect the four standards together. converge in an upward direction as usual and they are diagonally braced by adjustable rods 4 having right and lefthanded threads upon the ends thereof engaging suitably anchored nuts 10. On one side of the derrick, provision has been made for receiving the walking beam as shown in Figure 1. In the illustrated construction, a pair of bracing members 3 are sufficiently spaced apart to allow for the oscillations of the walking beam, and a pair of spaced and parallel struts 5 are secured to the said members 3, and short braces 6 connect the struts with the standards 1, short diagonal bracing rods 7 having right'and left handed threads, connect the struts 5 with the standards 1 in a manner similar to the tie rods 4. The walking beam is designed to extend through the space between the struts 5. The bracing or tie rods and 7 are adjustably anchored to the vertical standards by means of angular anchor lugs 8 whichare bolted over the corners of the standards 1 or over the corners of the members 3 as shown in Figures 2 and 3. Angle plates 19 are pref erably positioned upon the inner corners of the standards 1 to protect the wood and form a solid bearing surface for the heads of the bolts 20 which secure the anchor lugs 8. and split resilient washers 2O may be used'to exercise an expansion force against the nuts 2,0 upon the bolts 20. These anchor lugs are in the form of castings, preferably steel, and each flange of each casting is provided with a terminal abutment 8 having suitable apertures to receive the tie rods. These abutments 8 are angular and so designed that the pull of the tie rod may be normal thereto. Integral ribs 8 extend from each abutment so that each tie rod hole will lie between a pair of ribs which are so spaced as to securely hold the tie rod nuts 10 against turning or working loose These standards and dropping down. In. other words these castings or anchor lugs may be Said to have anchoring pockets for tie rod nuts.

Anchor lugs 9 connect the tie rods 7 with the vertical struts These anchor lugs 9 are similar to the anchor lugs 8 excepting that they are not angular since they are designed to support but a single pair of tie rods. These anchor lugs may be variously arl 'anged and spaced as desired and any number may be used according to the number of tie rods desired. In Figure 1 the integral ribs 8" are not shown on the castings 8 and 9 since the scale of the drawing is too small, and confusion might occur.

The head or upper structure of the derrick which is bestshown in Figures 5 and G will now be described. In reterring to said figures, it will be observed that a pair of. beams 11 rest across the tops of the front and rear standards 1, The ends of these beams are rabbeted upon. their inner sides for receiving the ends of beams 12 each 01" which i supp r ed by a front and rear standard, at right angles to thebeams 11. Tie rods 13 connect the blocks 15 While tie rods 14- connect the beams 12. Header blocks 15 are superposed upon the front and rear beams 11 and angle plates 16 are bolted upon the upper corners of the standards 1. These angle plates extend over the outer corners of the front and rear beams 11, and partially encompass the header blocks 15, to Which the same are bolted,

Angular anchor lugs 17 are secured to the upper corners of the angular plates 16. These anchor lugs 17 are somewhat similar to those previously described, in that they have nutpockets formed by the abutment 17 and ribs l7 Which are suificiently spaced apart to receive a tie rod nut 10 therebetween for confining the same against rotation and working loose and dropping down. These anchor lugs 17 are designed to secure but a single tie rod; each one securing the upper end of the upper tie rods.

It will be appreciated that by using right and left handed threads upon the ends oi the tie rods, and anchoring the nuts in the anchor blocks, it will be possible to tighten these rods by applying a Wrench and rotating the same. And as these castings are securely bolted and the nuts anchored thereon there is little liability of the same Working loose and dropping down and injuring a Workman. It Will also be appreciated that the manner of securing the beams 11 com monly called the dead Wood prevents the same from Working loose and dropping down as has previously happened in other structures, and injuring a workman.

I am aware that many changes may be made, and numerous details of construction may be varied through a Wide range Without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim:

1.. A tie rod anchoring lug for a Well drill.- ing derrick comprising an angular casting having right angled flanges adapted for at taclnnent to the corner of the derrick, each flange terminating in an apertured abutment for receiving the ends of tie rods and nut anchoring pockets behind said abutments for receiving the tie rod nuts.

2. A tie rodanchoring lug for a Well drilling derrick comprising an angular member having right angled flanges, each terminat ing in an apertured abutment, and ribs extending from said abutments on opposite sides of saidapertures for forming nut re ceiving pockets.

In testimony whereof I have hereunto subscribed my name.

DA-LLAS D. VWERTZBERGER.
